 |I must have misread.  The iana link above clearly has submissions =
 |465/tcp.  It also has urd.  So our file should of course match.

465 is urd and submissions and igmpv3lite (here).
But since MTAs do not look out for smtps (instead of 465 for SMTPS
we now have RFC 8689, SMTP Require TLS Option --- hihihi) it does
not matter to also give SMTPS that MUAs may look out for (which
normal mentally healthy user looks for submissions:// given he
normally uses smtp:// even though that most likely is indeed
submission or so, who knows, .. luckily my hairsplitting time has
long passed).

Did you not ask Christos Zoulas, he surely "did something" the
last time this came up.

Maybe that is in "othersrc" or any other such thing i do not
track.

What i did not understand was that huge number of additional name
permutation entries we see.
